Constructed from aluminum oxide abrasive with a vitrified bond, this wheel delivers consistent stock removal on ferrous metals and tool steel. It runs at a maximum of 5,730 RPM and carries a medium hardness rating (Hardness Code I), making it well-suited for controlled material removal without excessive wheel wear. The specification designation is 32A46-IVBE. At 0.804 pounds, the wheel is compact and designed to mount on bench grinders or tool and cutter grinders. Licensed trades and skilled machinists are the primary installers and operators of this wheel.\u003c\/p\u003e\u003cp\u003eThis grinding wheel is used in tool rooms, maintenance shops, and manufacturing environments where precision grinding of cutting tools, drill bits, and similar workpieces is required. The Type 11 cup shape provides a large contact face for grinding relief angles and flat surfaces on tooling. The 46-grit aluminum oxide abrasive is appropriate for coarse-to-medium material removal on carbon steel, alloy steel, and hardened tool steel. It is a single-unit item suited for both production grinding and maintenance sharpening tasks.\u003c\/p\u003e\u003ch4\u003eKey Features\u003c\/h4\u003e\u003cul\u003e\n\u003cli\u003eType 11 flaring cup geometry for tool and surface grinding applications\u003c\/li\u003e\n\u003cli\u003e46-grit aluminum oxide abrasive with vitrified bond for consistent cut rate\u003c\/li\u003e\n\u003cli\u003eMedium hardness (Code I) balances wheel life and cutting efficiency\u003c\/li\u003e\n\u003cli\u003eMaximum operating speed of 5,730 RPM\u003c\/li\u003e\n\u003cli\u003eNon-porous construction for clean, controlled grinding action\u003c\/li\u003e\n\u003cli\u003eSpecification designation 32A46-IVBE for cross-reference and replacement matching\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch4\u003eCompatibility\u003c\/h4\u003e\u003cp\u003eDesigned as an OEM-style replacement or standard-stock grinding wheel for bench grinders and tool and cutter grinders accepting a Type 11 cup wheel with a 1-1\/4 inch arbor hole and operating within a 5,730 RPM maximum speed rating.\u003c\/p\u003e\u003ch4\u003eInstallation Notes\u003c\/h4\u003e\u003cp\u003eGrinding wheel mounting and dressing should be performed by a qualified operator following ANSI B7.1 safety standards for the use, care, and protection of abrasive wheels.
